Aha!
1:39:07pm argus(1): cd /usr/ports
1:39:11pm argus(2): make search name=lsof

Path: /usr/ports/sysutils/lsof
Info: Lists information about open files (similar to fstat(1))
Maint: ler@lerctr.org

WWW: http://people.freebsd.org/~abe/
Port: p5-Unix-Lsof-0.0.5_1
Path: /usr/ports/sysutils/p5-Unix-Lsof
Info: Unix::Lsof -- a wrapper to the Unix lsof utility

Next time, please state that it is a port and not a builtin.
